Objectives: The aim of this study was to compare the diagnostic accuracy of the Diagnocat system (DGNCT LLC, Miami, Florida, USA), based on artificial intelligence algorithms, with clinical assessments performed by three dentists. Materials and Methods: The analysis was based on data obtained from cone-beam computed tomography (CBCT), focusing on the detection of carious lesions. The inclusion of three specialists with comparable levels of knowledge and professional experience increased the reliability of the results. The dentists classified teeth with carious lesions solely on the basis of CBCT imaging, physical examination, and their own clinical knowledge, under single-blind conditions, without awareness of the subsequent comparative analysis. Results: The results demonstrated a variable level of agreement between the Diagnocat system and the dentists’ assessments, depending on factors such as tooth location, as well as patient age and gender. The lowest level of agreement was observed in premolars, which may be attributed to their complex morphology. Higher diagnostic accuracy was noted in molars and incisors, particularly in younger patients. Conclusions: Further research should focus on the integration of various diagnostic modalities, including diagnostic imaging, intraoral scans, and photographic documentation, which may significantly enhance diagnostic precision, especially in cases of early-stage lesions. According to the results, the Diagnocat system demonstrates potential as a supportive tool in the diagnostic process in dental practice, as well as a screening tool enabling preliminary evaluation of imaging studies.

Background: The evolution of digital dentistry has enabled the development of more predictable and less invasive protocols for bone augmentation and prosthetic rehabilitation. This case report introduces an integrated digital workflow combining the Digital CarroTrack technique with the “One-Step Crown” concept to optimize clinical outcomes and efficiency. Case Description: A patient requiring alveolar ridge reconstruction and implant therapy was treated using the Digital CarroTrack technique. This approach utilized precise digital planning to simultaneously harvest an autogenous bone cylinder from the surgical site and reposition it for augmentation, eliminating the need for a secondary donor site. Following implant placement, a “one-step crown” protocol was implemented. A provisional restoration served as a template for soft tissue contouring, and its emergence profile was directly replicated in a pre-designed definitive crown. The bone cylinder fixation screw was retrieved during the final prosthetic delivery, ensuring a streamlined workflow. Results: In this case, the integrated digital approach facilitated accurate bone cylinder placement and implant positioning. At the 2-year follow-up, clinical and radiographic examinations confirmed excellent stability of both hard and soft tissues, with no marginal bone loss or soft tissue recession. The procedure reduced the number of clinical stages, treatment time, and patient morbidity compared to traditional methods. Conclusions: This case report suggests that the combination of the Digital CarroTrack Technique and the One-Step Crown concept may represent a promising, minimally invasive, and time-efficient approach for complex implant-prosthetic cases. Digital planning appeared to support procedural accuracy while reducing surgical invasiveness and the number of clinical stages. Further prospective studies with larger patient groups, objective volumetric measurements, longer follow-up, and dedicated cost-effectiveness analyses are needed to confirm the predictability, clinical effectiveness, and potential economic benefits of this approach.

Background and Clinical Significance: Peri-implantitis is an inflammatory condition associated, among other factors, with biofilm accumulation, affecting peri-implant soft and hard tissues and potentially leading to implant loss. Its treatment remains challenging because no single decontamination or regenerative protocol has demonstrated clear superiority. This case report describes a comprehensive surgical and regenerative approach aimed at preserving an affected implant and restoring peri-implant tissue stability; Case Presentation: A systemically healthy 30-year-old patient presented with peri-implant bone loss around an implant in position 25, restored with a lithium disilicate crown and functioning for three years. Treatment included flap elevation, mechanical debridement and air-polishing of the implant surface, followed by thorough irrigation with sterile saline to remove residual abrasive particles and debris, photodynamic antimicrobial therapy, and laser therapy. Bone regeneration was performed using a bone substitute combined with injectable platelet-rich fibrin to produce sticky bone, which was covered with an advanced platelet-rich fibrin membrane. A provisional crown was placed without occlusal contact. After four months, a definitive crown with a modified emergence profile was delivered to improve hygienic access and reduce biofilm retention. Clinical and radiographic follow-up over five years demonstrated stable peri-implant tissues and maintained bone levels; Conclusions: The combined use of surgical decontamination, PRF-assisted regeneration, sticky bone, and prosthetic modification resulted in stable clinical and radiographic outcomes over five years. Identification and elimination of contributing factors were essential for long-term treatment success.
